Installing the speed and position sensors
 
Reed contact sensors are suitable as speed and position sensors.
 
 
 
 
Functional principle
 
 
A signal is sent when the red side of a magnet is held in front of the red cap of the sensor. This creates a connection between the signal line and the ground wire of the sensor.
